【摘要】 用熔融结晶技术从DDHI混合物中分离提纯人造麝香DDHI,结晶的适宜条件为 :结晶时间2h ,降温速率 4℃ /h ,通氮气 ,发汗时升温速率为 6℃ /h ,发汗时间为 30min。经过二级结晶 ,w(DDHI) =99 2 % ,收率为 6 3 2 %。更多还原

【Abstract】 Melt crystallization was used to purify mixture of musk DDHI.It was shown that the appropriate operation conditions were crystallizing time 2 h,cooling rate 4 ℃/h for crystallization,heating rate 6 ℃/h for sweating,and sweat time 30 min.After crystallization,purity of the product was higher than 99 2%,and the yield was 63 2%.更多还原
